Compare and contrast primary and secondary succession of an ecosystem. What is the distinction between them?
primary succession is the sequence of species that become established early in a newly colonized area, while secondary succession is the sequence of species that move in much later.
primary succession is the establishment of a new community in an existing ecosystem that was disturbed, while secondary succession is the establishment of a community in an area that was altered due to fire.
primary succession is the establishment of a community in an area with no soil, while secondary succession is the establishment of a new community in an existing ecosystem that was disturbed by some catastrophic event.
